[0002] A metal pipe processing clamping device is a device used to fix metal pipes, enabling the metal pipes to remain stable during the processing, preventing the metal pipes from moving or deforming, and causing defective products. It plays an important role in the production and processing of metal pipes. The design and application of the metal pipe processing clamping device are crucial for improving the processing accuracy and production efficiency of metal pipes, and it is an indispensable clamping device during the processing of metal pipes.

[0003] Most of the chucks of metal pipe processing clamping devices are arc-shaped or triangular in appearance, which can increase the contact area between the chuck and the metal pipe and can fix the metal pipe better. When it is necessary to clamp metal pipes with different diameters, it is necessary to replace the matching chuck. However, most of the connection methods of the chuck are connected to the clamping device through bolts. When replacing the chuck, it is necessary to disassemble all the bolts, which is very time-consuming. To solve this technical problem, the utility model proposes a metal pipe processing clamping device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a metal pipe processing clamping device, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-6 shown, a clamping device for metal tube processing includes a base plate 1, an arc-shaped clamping block 2 and a mounting base 3. A gantry 4 is connected to the upper surface of the base plate 1. A sliding plate 5 is arranged inside the gantry 4. A roller 12 is rotatably connected to the inner side of the sliding plate 5. The outer surface of the roller 12 is in sliding contact with the inner wall of the gantry 4. The sliding plate 5 contacts the gantry 4 through the roller 12. The rolling function of the roller 12 can reduce the friction with the gantry 4, and the stability of the sliding plate 5 can be improved through the support of the roller 12.

[0025] A lead screw 10 is threadedly connected to the inner side of the gantry 4. The other end of the lead screw 10 is fixedly rotatably connected to the upper surface of the sliding plate 5. One end of the lead screw 10 located outside the gantry 4 is movably connected to a force-applying rod 11. The power provided by the rotation of the lead screw 10 is used to push the upper arc-shaped clamping block 2 to move up or down. The force-applying rod 11 can improve the power output of the lead screw 10. The gantry 4 has a supporting function. The gantry 4 provides a guiding direction for the sliding of the sliding plate 5 and improves the stability of the sliding plate 5 during sliding. There are two mounting bases 3. The mounting bases 3 provide a supporting force for the arc-shaped clamping block 2. One of the mounting bases 3 is connected to the upper surface of the base plate 1, and the other mounting base 3 is connected to the lower surface of the sliding plate 5. T-shaped mounting grooves 6 are formed in the inner sides of the two mounting bases 3. The stability of the T-shaped sliding blocks 7 is improved through the T-shaped mounting grooves 6. T-shaped sliding blocks 7 are slidably connected to the inner walls of the two T-shaped mounting grooves 6. Arc-shaped clamping blocks 2 are connected to one sides of the two T-shaped sliding blocks 7 located outside the mounting bases 3. The stability of the arc-shaped clamping blocks 2 is provided by the T-shaped sliding blocks 7. Arc-shaped clamping blocks 2 of various different specifications can be customized according to requirements.

[0026] The interior of the mounting base 3 is provided with a fixing mechanism 9. The movement position of the T-shaped slider 7 is restricted by the fixing mechanism 9 to improve the stability of the T-shaped slider 7. The fixing mechanism 9 includes a base 901. One side of the base 901 is connected to the inner bottom wall of the mounting base 3. The inner fixed point of the base 901 is rotatably connected to a pressing plate 902. One side of the pressing plate 902 is connected with a clamping block 903. The base 901 provides support for the pressing plate 902, enabling the pressing plate 902 to have a rotating function. The rotation of the pressing plate 902 is actually a small-range swing. By swinging the position of the pressing plate 902, the position of the clamping block 903 is controlled. The other side of the pressing plate 902 is connected with a spring 904. The other end of the spring 904 is connected to the inner bottom wall of the mounting base 3. When the pressing plate 902 moves towards the inside of the mounting base 3, the spring 904 is compressed. After the external pressure on the pressing plate 902 is lost, the spring 904 pushes the pressing plate 902 to reset. The spring 904 provides power for the reset of the pressing plate 902. A clamping groove 905 is formed on the inner side of the T-shaped slider 7. The inner wall of the clamping groove 905 is in contact with the outer surface of the clamping block 903. One side of the T-shaped slider 7 is connected with a baffle 906, and the baffle 906 is located above the pressing plate 902. By the contact between the clamping block 903 and the clamping groove 905, the movement of the T-shaped slider 7 is restricted, and the stability of the T-shaped slider 7 is improved. The baffle 906 can prevent a metal pipe or other objects from contacting the pressing plate 902, causing misoperation, resulting in the pressing plate 902 pressing down the clamping block 903 to disengage from the clamping groove 905, causing the T-shaped slider 7 to lose the fixing restriction.

[0027] A fixing pin 13 is connected to the outer surface of one of the arc-shaped clamping blocks 2. A fixing groove 8 is formed on the inner side of the other arc-shaped clamping block 2, and the fixing groove 8 is adapted to the fixing pin 13. After the upper arc-shaped clamping block 2 moves downward and contacts the lower arc-shaped clamping block 2, the metal pipe is clamped. At the same time, the fixing groove 8 is inserted into the fixing groove 8, and the fixing pin 13 is wrapped inside by the fixing groove 8, so that the two arc-shaped clamping blocks 2 are tightly connected together, improving the stability of the two arc-shaped clamping blocks 2 when clamping and fixing the metal pipe.

[0028] It should be noted that in actual use of this device, first place the metal tube in the lower arc-shaped clamping block 2, then rotate the screw rod 10 through the force-applying rod 11. While the screw rod 10 rotates, it pushes the sliding plate 5 to move downward. At the same time, the sliding plate 5 pushes the upper arc-shaped clamping block 2 to move downward. Subsequently, the upper arc-shaped clamping block 2 contacts the lower arc-shaped clamping block 2 to clamp and fix the metal tube. At the same time, the fixing pin 13 is inserted into the fixing groove 8. When it is necessary to fix metal tubes with other diameters, the arc-shaped clamping block 2 needs to be replaced. First, press the pressing plate 902 to swing. While the pressing plate 902 swings, it drives the clamping block 903 to disengage from the clamping groove 905. At the same time, the pressing plate 902 compresses the spring 904. After the clamping block 903 disengages from the clamping groove 905, the T-shaped slider 7 is not blocked. Pull the arc-shaped clamping block 2 to move. At the same time, the arc-shaped clamping block 2 drives the T-shaped slider 7 to disengage from the T-shaped installation groove 6. Then take the required arc-shaped clamping block 2. When placing it, first place the T-shaped slider 7 into the T-shaped installation groove 6. When placing it again, the T-shaped slider 7 pushes the pressing plate 902 to move. After the T-shaped slider 7 moves into the T-shaped installation groove 6, the spring 904 pushes the pressing plate 902 to reset. At the same time, the pressing plate 902 pushes the clamping block 903 to contact the clamping groove 905 to limit the movement position of the T-shaped slider 7. At the same time, the T-shaped slider 7 limits the movement position of the arc-shaped clamping block 2.
